ROTATING SIGN.

Specification of Letters Patent.

Patented Aug. at, 1914.

Application filed December 15, 1913.1 Serial No. 806,817.

To all whom it may concern Be it known that I, J onn Srermnn KnN- DALL,of the city of Hamilton, in the county of lVentworth, in the Province ofOntario, Canada, have invented certain new and useful Improvements inRotating Signs, of which the following is the specification.

My invention relates to improvements in rotating signs, and the objectof the invention is to devise a sign which will intermittently rotateand disclose different advertisements to view; a further object is toconstruct a sign in which the advertisements will be illul'ninated andalso to provide means for throwing the lamp out of circuit when the signis rotatin The invention consists of a wheel carrying the advertisingsigns, means for driving the wheel from an electric motor or othersource of power, brackets extending outwardly from the periphery of theaforesaid wheel, means connected to the driving means for engaging thebrackets when they are in a certain position, said means being designedto be released from engagement with the brackets when the wheel has beenrotated a requisite extent, and means for electrically connecting a lampmounted. on the afore said wheel to an electric light circuit Wherebythe lamp is adapted to be lighted when an advertising sign is inposition and to be out when the sign is being rotated, said wheel beingmounted eccentrically of the said driving means, all as hereinafter moreparticularly described and illustrated in the accompanying drawing, inwhich 2- Figure 1 represents a side elevation of a sign constructedaccording to my invention. Fig. 2 is a plan view thereof. Fig. 3 is aperspective view of one of the brackets showing contact fingers adaptedto connect the lamp with an electric light circuit and Fig. l is anelevation of a portion of the sign showing a modified form. Fig. 5 is adiagrammatic view of the electrical connections between the lamp and theelectric light circuit. Fig. 6 is a perspective detail of a rollerpivotally mounted on a pin connected to the driving means, said rollerbeing adapted to engage the aforesaid brackets.

Like characters of reference lndlcate correspondlng parts 1n thedifferent views.

1 is the f 'ame of the sign which in the present instance is dividedinto four sections 2 constructed of transparent material and adapted tocarry advertising matter.

3 is a wheel freely mounted on the vertical shaft l. 5 is an electriclamp socket suitably mounted on the said wheel and (3 is an electriclamp bulb.

7 is a motor.

8 is a fixed vertical shaft mounted on the bracket 9.

10 is a large pulley wheel freely mounted on the shaft 8 and 11 is asmall pulley wheel keyed to the motor shaft.

12 is a belt connecting the pulley \vl1eel10 with the pulley wheel 11.

13 is a small pulley wheel mounted on the top of the aforesaid pulleywheel 10, and consequently free of the shaft 8.

14; is a vertical fixed shaft mounted on the bracket 15. i

16 is a pulley wheel freely mounted on the shaft 14, and 17 is a smallpulley wheel connected thereto and consequently free of the shaft ll.

18 is a belt connecting the pulley wheels 13 and 16 together.

19 is a large pulley wheel freely mounted on the shaft 8 above theaforesaid pulley wheels 10 and 13, and 20 is a belt connecting thepulley wheel 19 with the pulley wheel 17.

21 is a bracket rigidly connected to the fixed shaft 8 and carrying theshaft t with which it is rigidly connected, it being understood that thewhecl 3 is freely mounted on the shaft f as above stated.

22,. 22 are outwardly extending brackets or plates secured to the wheel3 and carrying the plates 23 constructed of suitable insulatingmaterial.

24, 24; and 25, 25 are upper and lower contact fingers respectivelyattached to the brackets 22 by the bolts 26 and insulated therefrom bythe plates 23 and 27.

28 is a vertical bracket carrying the upper and lower contact fingers 29and 30, said contact fingers being either insulated from the saidbracket .28 or the said bracket being constructed of insulatingmaterial. The

contact fingers 2S) and 30 are connected to the wires 31 and 32 whichare in turn connected to an electric l ght circuit.

33, 33 are wires connecting the lower contact fingers 25 with one of theterminals of the lamp 6, and 34, t are wires connecting the upperconttct fingers 2% with the other terminal of the lamp.

35 is an upwardly extending vertical pin suitably mounted on the rim ofthe pulley wheel 19, and 36 is a horizontal roller pivotally mounted onthe top of said pin.

From the above description it will be seen that the wheel 3 iseccentrically mounted in relation to the pulley wheels and 19 which aremounted on the shaft 8.

in the modification shown in Fig. 4 a small casing 37 is mounted on thewheel 3 and is provided with a series of lenses 38 carrying theadvertising matter, it being understood that the casing 3? surrounds thelamp 6 and the letters of the advertisement are adapted to be projectedon to a ground glass filling the aperture in the inclosing casing.

The operation of the device is as follows :lVhen the sign is in theposition shown in Fig. 1 or Fig. 2, the lamp 6 is lighted as the contactfingers 24 and 25 are in engagement with the contact fingers 29 and 80respectively, which as above described are connected to the electriclight circuit by the wires 31 and 82, but as will hereafter be apparentthe lamp 6 goes out when the sign is rotated and does not light againuntil the next set of contact fingers 24 and 25 come into contact withthe contact fingers 29 and 30. Further it is to be unoerstood that themotor circuit is an entirely separate circuit from the electric lightcir cuit and when the current is turned on and the motor revolved thepulley wheel 10 freely mounted on the shaft 8 will be revolved, as it isconnected to the motor pulley 11 by the belt 12. The pulley wheel 13which is connected with the pulley wheel 10 will also be revolved andconsequently the pulley wheel 16 which is connected thereto by the belt18. As the pulley wheel 17 is mounted on the pulley wheel 16 this willalso be revolved and consequently the upper pulley wheel 19 which isconnected to the pulley wheel 17 by the belt 20 will be revolved. Aswill be apparent the reason for using the above arrangement is to reducethe speed of the pulley wheel 19 in relation to the motor pulley wheel11, and when the roller 36 comes into the position shown in Fig. 2 itwill engage a bracket 22 on the wheel 3 and will thus revolve this wheelun til the bracket comes into position at right angles to its initialposition when the roller will roll ofl. the bracket and consequentlyallow the wheel to stop. It will be seen that this will take place, asthe wheel 3 is eccen trically mounted in relation to the pulley wheel19. Now when this movement takes place a set of contact fingers 24 and25 will come into engagement with the contact fingers 29 and 30 and thelamp 6 will be lighted again, thus disclosing the advertisement. Afterthe roller has been released from the bracket it will not engage anotherbracket until the pulley wheel 19 has made three quarters of arevolution when the roller 36 will again come into the position shown inFig. 2 and will engage the next bracket, consequently the lamp will belighted and each advertisement will appear for a certain time.

It is to be understood that the device can be arranged so that the signwill either op-. erate more quickly or more slowly as is shown in thepresent instance. Further any number of signs can be constructed and thedevice arranged and timed so as to show each in turn.
